# On comparing the ratios and find out whether the following pair of linearequations are consistent, or inconsistent.(i) (ii) (iii) (iv) (v)

(i) We get,

=

=

Hence,

=

Therefore , these linear equations will intersect at one point only and have only one possible solution and pair of linear equations is inconsistent.

(ii) We get,

=

=

=

Hence,

=

Therefore, these linear equations are parallel to each other and have no possible solution.

And pair of linear equations is inconsistent.

(iii)

9x – 10y = 14

We get,

=

=

=

Hence,

=

Therefore, these linear equations will intersect each other at one point and have only one possible solution.

And, the pair of linear equations is consistent.

(iv) We get,

=

=

=

Hence,

=

Therefore these pair of lines has the infinite number of solutions. and pair of linear equations is inconsistent

v) We get,

=

=

=

Hence,

=

Therefore these pair of lines have infinite number of solutions and pair of linear equation is consistent.
